ABSTRACT

Objective: To analyze the role of low-dose CT combined with serological indexes in the diagnosis of lung cancer. Methods: 67 patients with lung cancer in our hospital from August 2019 to August 2021 were selected as group A, and 67 healthy persons accepting physical examination in our hospital during the same period were selected as group B. Low-dose CT scanning and serological index detection were performed. The serological indexes of the two groups were compared, and the diagnostic accuracy of low-dose CT simple scanning and combined diagnosis for lung cancer was compared. Results: The levels of serological indexes in group A were higher than those in group B (P < 0.05). Taking surgical pathology as the gold standard, the accuracy and sensitivity of combined diagnosis were higher than those of low-dose CT scanning (P < 0.05). The image quality of low-dose CT scanning was excellent, accounting for 77.61% (52 / 67), and the size of nodules could be clearly detected. Conclusion: Low-dose CT combined with serological index detection can improve the diagnostic accuracy, and the serological indexes of lung cancer patients is higher. The image quality of low-dose CT scanning is better and lung cancer diseases can be effectively detected through joint diagnosis.
